What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at how a special heart device (BackBeat CNT) affects nerve activity in 15 people with high blood pressure who already have the device implanted. Researchers measure nerve signals and blood pressure with and without the device turned on. The goal is to understand how the device works, not to test a new treatment.

Participants

About 15 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2022

Expected to finish

May 2027

An estimate. End dates often move.

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.

Inclusion Criteria: * Subject is already implanted with a Moderato IPG that can be used to deliver CNT pacing signals, whether CNT pacing was activated or not. * Subject is willing and able to comply with the study and procedures. Exclusion Criteria: * Subject is dependent on 100% ventricular pacing. * Subject has symptoms of heart failure, NYHA Class III or greater. * Subject has an ejection fraction of 25% or less * Subject's systolic blood pressure is less than 100 mm Hg on the day of recording. * Subject has decompensated heart failure * Subject has significant (\>3+) mitral regurgitation, aortic regurgitation, or aortic stenosis * Subject has permanent atrial fibrillation. * Subject has Atrial fibrillation on the day of the study. * Subject has hypertrophic cardiomyopathy, restrictive cardiomyopathy, or interventricular septal thickness ≥15 mm. * Subject is on dialysis * Subject has prior neurological events (stroke or TIA) within the past year or a neurological event (stroke) at any prior time that has resulted in residual neurologic deficit. * Subject has a history of autonomic dysfunction. * Women who are pregnant or breast-feeding. * Subject cannot or is unwilling to provide informed consent
